Architecture is broadly defined as a science of designing and building structure. It is process of planning, designing, and constructing the structure. In software field structure is the software application. In simple term, Software is computer programs and data that tells computer to perform series of actions using underlying hardware. In real world, there are multiple computer programs executed in chronological order. In real world, software applications which are solving any business requirement is very complex where multiple software applications, commonly called as building blocks are integrated with each other. Software architecture is encompassing the high-level organizations of its components, how they interact and principles guiding their design. This paper present guidelines on architecture where data integrity is extremely important. Correct and adequate data should be presented and maintained in application.
